classic roadster cobra rims and tires size

[Sycraft]

Want to resurrect this old thread.. I measured my rims. Front 15" with 4 3/8 backspacing.. rear 15" with a needed 5.25 backspacing. They have 5.5 but require a 1/4 spacer to clear brakes and not rub. Wan ti go to pin drive and want to make the right choice. Pics later

Sycraft, I am in the same position. My car should come back from paint within a few weeks. Then, its on to final assy and new wheels/tires. I have a set of Cobra II 5 pin wheels with the 1/4" adapters. It looks like the rears will only take 275 on my ca as well.

Hope others will chime in here soon.
